I have a Norfolk pine who has 4 main branches. 2 of them are thriving greatly and one is getting completely crispy, which is also a cross branch at the base. The fourth branch is very short and mostly okay, looks like he's getting a little dry, and possibly a tad yellow upcoming. There is no full yellow or brown on the entire tree. It does reside indoors with a 65-72 degree temp and on a table behind a tree like plant which sits between the pine and the window. I mist the tree every few days and water about once a week when I see the top level is dry. Any help would be greatly appreciated!
